Comet vs. Asteroid
... Comet vs. Asteroid A comet is a small solar system body. They can be as small as 100 meters or as big as 40 kilometers across. They have such low mass that they do not become spherical, or round. Most comets have elliptical orbits around the sun. Some comets have 200-year orbits, and others take mil ...

Rosetta (spacecraft)
Rosetta is a robotic space probe built and launched by the European Space Agency. Along with Philae, its lander module, Rosetta is performing a detailed study of comet 67P/Churyumov–Gerasimenko (67P). It also performed a flyby of Mars and the asteroids 21 Lutetia and 2867 Šteins. On 12 November 2014 the mission performed the first successful landing on a comet. As of 2015, the mission continues to return data from both orbit and the comet's surface.
